Quick, new refs
Some new refs with lots more to come soon.
In the 18Aug95 issue of science there is a report on latest Ancient DNA
conference (I got to go to the one here a few years ago - it was fun!)
Williams, Nigel. 1995. The trials and tribulations of cracking the
Prehistoric code. Science 269:923-924.
They seem to be arguing more hotly than ever about whether anything over
100,000 years is any good. This should be interesting.
Then Walter Alvarez and crew have a long and interesting paper about
Chicxulub and why a warm accelerating fireball should solve 3 major problems
with the impact data - that some shocked quartz in N. Amer. occurs above
the boundary, why it's more abundant West than East, and how it could
withstand initial velocities that should have melted it.
Alvarez, W., P. Claeys & S.W. Kiefer. 1995. Emplacement of Cretaceous -
Tertiary Boundary Shocked Quartz from Chicxulub Crater. Science 269:930-935.
And finally for now (more coming...)
Cook, E. 1995. Taphonomy of two non-marine Lower Cretaceous bone
accumulations from southeastern England. Palaeo, Palaeo, Palaeo
sorry thats Palaeogeography, Palaeoclimatology, Palaeoecology
Two Wealden outcrops are very different in their taphonomy as indicated by
their dinosaur and other bone materials. One appears to be a fluvial high-
energy lag (lots o' abrasion) and the other a low-energy overbank
deposit with less abrasion but more subaerial weathering. Neato for us
More to come, Your pal, Ralph Chapman, NMNH
The question of the week is "Will the US Gov't shut down on Oct. 1?"
or put another way, "Is the USA really a third world power?"
